Fedora 45 : perl-Crypt-DSA (2026-cf622b92d7)

critical Nessus Plugin ID 321099

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 45 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2026-cf622b92d7 advisory.

 Automatic update for perl-Crypt-DSA-1.21-1.fc45.

 ##### **Changelog**

 ```
 * Mon Jun 15 2026 Paul Howarth <[email protected]> - 1.21-1
 - Update to 1.21
 - Fixed key material reuse for multiple signing events (CVE-2026-12205, CWE-323)
 - sign() reused the DSA nonce k across signatures (r and k^-1 were cached on the key and not regenerated), allowing private-key recovery from two signatures over different messages
 - Now generates a fresh nonce per signature
 - Keys used to sign more than once with an affected version should be considered compromised
 * Fri Jun 12 2026 Yaakov Selkowitz <[email protected]> - 1.20-2
 - Rebuilt for openssl 4.0

 ```

Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution
